the following calendar month after being earned. Unlike Tesco petrol vouchers the Fuel Save savings could be used at the Pay@Pump. Exclusions from the £50 spend included Tobacco, Lottery, Gift Cards, Baby Formula Milk and Fuel. The scheme ended on 31 August 2015, with redemptions available until 30 September 2015. In-store Clubcard Boost Formerly known as the 'Double Up', then relaunched as the 'Clubcard Voucher Exchange', the Clubcard Boost was the new name for Clubcard Rewards; it launched in 2013. The Clubcard Boost in-stores works the same way as the previous schemes (for every £5 in Clubcard Vouchers, customers receive £10 in Clubcard Boost tokens). As with previous schemes there are only selected departments included: Baby & Toddler, Cosmetics & Fragrance, Clothing, Opticians, and Cook, Home & Dine. The In-store scheme has since ended, although the online scheme where customers can exchange Clubcard vouchers for up to 3 times their value at other retailers is still available. Privacy concerns Some Clubcard users have concerns about the information Tesco and Dunnhumby hold and what they do with it. Details of each Clubcard transaction, such as the store, products purchased, and price paid, are stored for up to two years. Applicants are asked to provide personal details such as name, address, and whether they have children. Tesco says this helps them pick vouchers that are relevant to the holder and to monitor trends to help product availability. Mobile phone applications Starting in the end of 2010, Tesco launched applications for iPhone, BlackBerry, Android (operating system) and Nokia Ovi, so points can be collected by presenting a barcode on the handset instead of a keyfob or card. This application was relatively simple on launch, offering little more than a barcode, but updates have increased functionality to include features such as the ability to view current offers instore. On 10 July 2017, Tesco released the Clubcard application on the Google Play store. Contactless Clubcard On 5 July 2017, Tesco announced a new contactless Clubcard. This follows a major user interface update of the Clubcard app. New customers can now use the Tesco Clubcard app to sign up to Clubcard straight away, while they shop in store. Existing customers can access their vouchers at the checkout. Tesco Pay+ In 2015, Tesco introduced a mobile app called PayQwiq. The app lets you pay for your shopping and collect your Clubcard points all in a single scan.
